摘要：
Sugar is one of the key nutrients required to microorganism growth. In this paper, the effects of various sugars on the mineralization of calcium carbonate induced by Bacillus pasteurii. The precipitation amount, forms and structures of calcium carbonate were characterized. The results indicated that the induced calcium carbonate precipitation are mainly calcite as irregular aggregated bodies and rhombus blocks and aragonite appeared when the culture medium was added with dextran. The calcium carbonate precipitation reached a maximum of 2.32 g when glucose was added into the culture.
